Mayor Bill de Blasio’s administration employs more than 50 drivers who are responsible for chauffeuring top New York City government officials, according to records released Friday.

The city has 53 full-time drivers and two part-time employees who serve as drivers for officials in a number of city agencies, according to the mayor’s office.

For example, Chancellor Carmen Fariña, who runs the nation’s largest public school system, has a full-time driver. Dr. Mary Bassett, commissioner of the Department of Health and Mental Hygiene, has a driver too.

Several officials in the mayor’s office have two drivers, including First Deputy Mayor Anthony Shorris and Press Secretary Phil Walzak.

The records released Friday don’t specify how many officials in the police or fire departments have drivers. The Wall Street Journal requested a list of all city officials who have drivers in January.

Though Gov. Andrew Cuomo is chauffeured by his security detail, no staff members of the governor’s executive chamber have full-time drivers, according to a spokesman for the governor. During previous administrations, the governor’s senior staffers were afforded drivers, but that practice was abolished at start of the Cuomo administration by Mr. Cuomo’s former top aide, Steven M. Cohen.

It was not immediately clear how many or which commissioners of state agencies have drivers.

In February, a WCBS-TV report alleged the mayor’s police-driven SUV speeded and violated other traffic laws after attending a news conference in Queens. At the time, Mr. de Blasio said his security detail and all city employees should abide by traffic laws, but the mayor said he wasn’t going to second-guess the actions of his security detail in any given moment.

“My message to my detail and all city employees is obey the law, drive in a way that is safe and be careful,” the mayor said this winter. “There’s no question about it.”

The WCBS-TV report came two days after the mayor outlined his plan to reduce traffic fatalities citywide. The administration is seeking permission from the state to lower the speed limit citywide to 25 miles an hour from 30. The Police Department is also be beefing up traffic law enforcement, specifically targeting speeding and drivers failing to yield to pedestrians.

On Friday, two of the three vehicles that were part of the mayor’s caravan were spotted running a red light after the mayor left a news conference. A spokeswoman for the mayor didn’t have an immediate response.

In 2004, after one of then-Mayor Michael Bloomberg’s deputy mayors was caught by WCBS using lights and sirens for nonemergency purposes, Mr. Bloomberg ordered the removal of police lights and sirens from 255 city vehicles.

Mr. Bloomberg’s decision left 73 civilian vehicles citywide equipped with the lights-and-sirens package. Only officials who respond to emergencies as part of their jobs were permitted to have the package.
